bidding,
Special Provisions Section 4, Special Provisions Section 10-1.38- Your
availability in providing the state furnished sign panels for overhead
signs 120 days after award and after notification is a potential delay
which seems inappropriate for A+B bidding on this job. Can the delivery
of these state furnished materials be revised to a more reasonable time,
for example, 20 work days after contractor's written request?

The State has a contract
with an outside sign supplier and it takes 120 days to furnish the signs
due to the ordering process, manufactering, and the delivering. Therefore,
this work should be bid in accordance to section 10-1.38 "Sign Panels,"
of the Special provisions.
